Lord Laidlaw's 1965 Porsche 904/6 Carrera GTS is better than coffee

That's the sound of a car that wins races.

This is the sound of a 50-year-old engine that makes 190 hp from 1.9 liters. It's the bleeding edge of mechanical engineering of the era. It's the sound of a giant killer.

For its sale of a collection of cars owned by Lord Laidlaw, RM Auctions has filmed a series of perfect little videos, each about 90 seconds, of the cars on track. They have done just exactly the right thing: It's all action, all car noises, and no music or narration. This is a pure injection of caffeine into a major artery, and it literally makes my heart beat faster. This 1965 Porsche 904/6 Carrera GTS is one of the most stunning in a stunning collection.
